Title: Two-stage production of thermoplastic polycarbonate
Inventor: SHIYUTEFUEN KIYUURINGU
IPC: C08G64/30
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a two-stage process for producing a lowly branched polycarbonate having a low degree of branching, a characteristic bright hue and a low terminal OH content by adopting a specified process in the melt transesterification process.  
     SOLUTION: In the first stage, a diphenol/diaryl carbonate mixture is mixed with 10 -2  to 10 -8 mol of a nitrogen phosphorus base as a catalyst, and then the temperature is raised to 290°C under a pressure of 100Pa to atmospheric pressure to remove the monophenol formed during the reaction by distillation to thereby give an oligocarbonate having a terminal OH content of 10-35mol%. In the second stage, this oligocarbonate is converted into a polycarbonate by a reaction 240-340°C for 10-60min under a pressure of 1-50,000 Pa in a self- cleaning high-viscosity reactor having a degree of self-cleaning of above 95% (based on the area) and an open effective capacity of at least 50%.

Abstract: PURPOSE:To reduce the size of a sheet material conveying device which includes a confluent position of convey passages. CONSTITUTION:An elastic member 5 is provided in a confluent position 3 of a first convey passage 1 and a second convey passage 2. The elastic member 5 is flexible, and is positioned in a closed position 5A where it engages with an engaging section 1C in its natural condition, and positioned in a retreat position 5B for a small load coming from the first convey passage 1 side, and in a pressed position 5C for a large load. On the other hand, it keeps the closed position 5A for any load coming from the second convey passage 2. When tip P1 of a sheet material P which is conveyed by convey rollers 7a, 7b makes the elastic member 5 to retreat and touches the nip section 9c of regist rollers 9a, 9b, a loop of sheet material P is formed at a confluence position 3, and the elastic member 5 in the pressed position 5C presses this loop to perform slant correction with the tip P1 serving as the standard. Thus, it is possible to make the regist rollers 9a, 9b approach the confluent position 3 and shorten mounting position L by adding oblique correction function to the elastic member 5.

Filed: 1981-06-02
Abstract: PURPOSE:To correct the rotation and the hair line of a beam spot by integrating an electrostatic tetrode into an electron gun, which is installed in an indexing color cathode-ray tube. CONSTITUTION:A cathode-ray tube with a unipotential-type electron gun has a neck part 1n, and an electron gun 21 which gives an electron beam spot having a long section.

The fourth grid G4 comes to have the effect of an electrostatic tetrode lens as well as a beam focusing effect by constituting an electrostatic tetrode 22 by dividing the grid G4 into four. As the result, by changing an electric potential applied to the grid G4 according to the deflection of the electron beam, the electron beam receives a rotational effect in the grid G4, both the rotation and the hair line of the beam spot developed at the diagonal corners of a picture surface are corrected simultaneously, and the color reproducibility is enhanced.

Title: Wiretapping device finder
Inventor: HARUYAMA SUKEAKI
IPC: H04M1/68
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a device for surely finding out a wiretapping device by inputting a radio wave signal transmitted from the wiretapping device by discriminating the presence/absence of the wiretapping device corresponding to whether the function value of mutual correlation between a demodulated audio signal and an audio signal from a telephone set is larger than a prescribed value or not. SOLUTION: When any radio wave signal such as the radio wave signal from a wiretapping device 23 is incoming, an antenna part 1 outputs the received signal, a high-band amplifier 2 amplifies the input signal, and a demodulation part 3 demodulates the audio signal. An input part 4 inputs the audio signal from a subscribed telephone set 21 through a modular cable and amplifies or attenuates it to a prescribed level. A mutual correlation function calculation part 5 calculates the function value of mutual correlation between the demodulated audio signal outputted from the demodulation part 3 and the audio signal outputted from the input part 4.  A detection part 6 compares this mutual correlation function value with a threshold value set in advance, discriminates whether the correlation is sufficiently high or not (whether the mutual correlation function value is larger than the threshold value or not) and outputs a detecting signal showing the discriminated result.
